INSTALLATION INSTRUCTIONS
SERIES NS4 FOUR WIRE APPLIANCES
(WALL MOUNT VERSIONS)
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Wheelock’s Series NS4 Horn Strobe Appliances are designed to provide independent operation for the horn appliance, when the
strobe circuit is powered. They are the ideal choice for retrofit applications as well as new installations. The NS4 Appliances are UL
Listed under Standard 1971 for Signaling Devices for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. The
1575W candela wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low
current draw. They are listed for indoor use only
and equipped with a NS Mounting Plate (NSMP) that can be mounted to single-
gang, double-gang, 4” backbox, 100mm European backbox or SHBB surface backbox (See Mounting Options). These appliances are
Listed for wall mounting only
. The NS4 Appliances use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan
lens to provide maximum visibility and reliability for effective visible signaling.
The horn portion of the NS4 Appliances can be field set to provide either Continuous Horn or Code 3 Horn. The sound output can be
field set for High (HI) or Low (LO) dBA.
The NS4 Horn Strobe can also be used with a Sync Module (SM) or Dual Sync Module (DSM) to provide synchronized strobe and
synchronized Code 3 signal.
These strobe models are designed for use with either filtered DC (VDC) or unfiltered Full-Wave-Rectified (VRMS) input voltage.
All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP.

WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL
INRUSH CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY
AND SECONDARY POWER SOURCES, SIGNALING CIRCUITS, SM AND DSM SYNC MODULES DO NOT EXCEED
THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO
WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS
COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
When calculating the total average, peak and inrush currents: Use Table 3 and 3A to determine the highest value of “Rated Average
Current” for an individual strobe (across the expected operating voltage range of the strobe), and use Table 3 to determine the highest
value of “Rated Inrush Current” or “Rated Peak Current” (whichever is higher) of an individual strobe (across the expected voltage
range of the strobe), then multiply these values by the total number of strobes; be sure to add the currents for any other appliances,
including audible signaling appliances, powered by the same source and include any required safety factors.
If the inrush current or peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies
may drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of
power supplies. For example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or
lack of battery backup across the output) may exhibit this characteristic.
CAUTION: Series NS4 are not designed to be used on coded systems in which the applied voltage is cycled on and off.

MOUNTING OPTIONS:
CAUTION: The following figures show the maximum number of field wires (conductors) that can enter the backbox used with
each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires
and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of
the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room
for easy installation and minimum stress on the product from wiring.

MOUNTING PROCEDURES:
CAUTION: Check that the installed product will have sufficient clearance and wiring
room prior to installing backboxes and conduit, especially if sheathed multiconductor
cable or 3/4" conduit fittings are used.
1. NS4 models have an integrated NS Mounting Plate (NSMP).
2. The NS Mounting Plate (NSMP) must be oriented correctly when it is mounted to the
backbox. Turn the NSMP so that the arrow below the word ‘‘Top’’ points to the top
side of the NSMP.
3 . NS4 models can be flush mounted to a standard single-gang backbox (Figure A), 4” or
100mm backbox (Figure B) or double-gang backbox (Figure C). NS4 models can also be
surface mounted to a 4’’ or 100mm backbox (Figure B), double-gang backbox (Figure C)
or the SHBB (Figure D).
4. Mount the NSMP first to the backbox. Next slide the Beauty Plate over the NSMP
until the 2 side snaps of the NS Beauty Plate engage with the NSMP.
5. The NS Beauty Plate can be removed from the strobe assembly once engaged. First,
gently insert a screwdriver into one of the slots located on the side edges of the NS
Beauty Plate. Second, gently pull away from the wall with the inserted screwdriver to
disengage the snap. Third, repeat the first and second steps for the second slot.
Finally, gently lift the Beauty Plate away from the NSMP.
6. Mounting hardware for each mounting option is supplied.
7. Conduit entrances to the backbox should be selected to provide sufficient wiring
clearance for the installed product.
8. When terminating field wires, do not use more lead length than required. Excess
lead length could result in insufficient wiring space for the signaling appliance.
9. Use care and proper techniques to position the field wires in the backbox so that
they use minimum space and produce minimum stress on the product. This is especially
important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
10. Do not pass additional wires (used for other than the signaling appliances) through
the backbox. Such additional wires could result in insufficient wiring space for the
signaling appliance.

hearing.
NS4-24110W strobe models are Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA
Standards and the Authority Having Jurisdiction.
WARNING: INSTALLATION OF WHEELOCK 110 CANDELA STROBE PRODUCTS IN SLEEPING AREAS
SHOULD BE WALL MOUNTED AT LEAST 24" BELOW THE CEILING AS FOLLOWS: (1) THE ON AXIS
(DIRECTLY IN FRONT OF LENS) LIGHT OUTPUT SHOULD BE DIRECTED AT THE EYE-LIDS OF THE SLEEPING
PERSON, E.G. PILLOW END OF BED, BED HEAD; (2) NO PART OF THE BED SHALL BE MORE THAN SIXTEEN
(16) FEET FROM THE STROBE NOTIFICATION APPLIANCE. INSTALLERS MUST ADVISE OWNERS AND
OPERATORS OF BUILDINGS WITH SLEEPING OCCUPANTS, E.G. HOTELS AND MOTELS, TO WARN GUESTS,
RESIDENTS AND EMPLOYEES TO NOT MOVE THE BED LOCATION TO A POSITION VIOLATING POINTS (1)
AND (2) ABOVE OR SERIOUS INJURY AND/OR LOSS OF LIFE MAY OCCUR DURING A FIRE EMERGENCY.
WARNING: A SMALL POSSIBILITY EXISTS THAT THE USE OF MULTIPLE STROBES WITHIN A PERSON'S
FIELD OF VIEW, UNDER CERTAIN CIRCUMSTANCES, MIGHT INDUCE A PHOTO-SENSITIVE RESPONSE IN
PERSONS WITH EPILEPSY. STROBE REFLECTIONS IN A GLASS OR MIRRORED SURFACE MIGHT ALSO
INDUCE SUCH A RESPONSE. TO MINIMIZE THIS POSSIBLE HAZARD, WHEELOCK STRONGLY RECOMMENDS
THAT THE STROBES INSTALLED SHOULD NOT PRESENT A COMPOSITE FLASH RATE IN THE FIELD OF VIEW
WHICH EXCEEDS FIVE (5) Hz AT THE OPERATING VOLTAGE OF THE STROBES. WHEELOCK ALSO
STRONGLY RECOMMENDS THAT THE INTENSITY AND COMPOSITE FLASH RATE OF INSTALLED STROBES
COMPLY WITH LEVELS ESTABLISHED BY APPLICABLE LAWS, STANDARDS, REGULATIONS, CODES AND
GUIDELINES.
NOTE: NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within
the same protected area.
CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or
restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system
communication circuits and/or audio circuits, for example, may require special precautions to assure electrical noise immunity (e.g.
audio crosstalk).
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital appliance, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
